Hi everyone, have a CPO 2019 GTS RWD Cab and I have a bunch of random questions...

1) I have found MANY threads about enabling android auto on this car. My car has carplay but I have an android phone. Its hard to tell what is the current options because things evolved over the years. I ordered the Ottocast x2 as recommended by many people but don't have high hopes based on all the problems people have had, not sure if current firmware works. I have found some people recommending paying a member but then I also found multiple posts on the internet on how it can be done with just an SD card. Also found a github repo by harman-f that looks promising. Is there a reason I would pay to have this done when it seems freely available to anyone with an SD card and some minor technical skill? If I want reliable android auto am I going to have to do the mod? Please help point me in the right direction for best option in 2024.

2) My car makes a fairly loud high pitch noise when i turn it off coming from the engine area. Goes away after maybe 5 minutes or so, is this normal?

3) my brake pads were "60%" according to the dealer. they work great but its driving me insane that they squeal every time i use them at low speed. my brakes announce me arriving into my neighborhood more than my exhaust. My sales rep said i just arent gettign them hot enough but they arent ceramic rotors, idk if the pads are ceramic.

Thanks everyone.

 

1) I did the mibroot hack on my 991.2's PCM4. There's a big thread about it but it's lacking some information and requires some programming chops to figure out. @simaservis1108 was, last I checked, the go-to person to just do this remotely for you. There have been improvements to the DIY process that sounded like it makes it way easier to do, but I haven't kept up. There are github repos about it, I'm sure you can find what you need searching 'mib2 hack' and stuff on the googles.

2) Record a video, post it to youtube, and link it here. I'd guess it's a failure of a check valve in your evap system, or perhaps your gas cap. Try opening your gas cap next time it's happening -- if it hisses loudly then stops the high pitch noise, you probably have an evap problem!

3) It's a common complaint, the owners manual also outlines that this is totally normal. There isn't really a permanent solution, it's just a byproduct of the size of the pads and rotors. Some people find that certain pad/rotor combinations make it quieter, but it never truly goes away. Go on an empty road and brake from 60 to 30 very hard 2 or 3 times, then drive for at least a few minutes at speed so they can cool off before you sit at a stoplight or stop sign with the hot brake pads just clamping against the hot rotors for an extended period. This will fix it for a week or so.

Welcome to Rennlist!

 

I bought the CPO + 1 so I am covered for 3 years, is anyone aware of anyone who ever had a warranty issue due to this android auto hack? I figure its worth a shot to try the Ottocast first, working wireless would be quite nice over wired but even in my mach-e which is a modern car built for wireless android auto its still incredibly unreliable so i dont have high hopes.

Here is the video that shows the sound:

 

I did the Ottocast first and have since done the MIB Hack. If you want to try Ottocast, I have one for sale, PM me.

 

I already ordered one from Amazon prime and I think I prefer that because I can easily return it and get my money back if I dont like the way it works.

Why did you deecide to do the MIB hack over the Ottocast?

How did you perform the MIB Hack? Which did you use?

thanks

 

I sent this in a PM to someone else asking my about AA. I have since switched from the wireless AA Ottocast dongle to AAWireless one (link below). The BT is not as aggressive and would recommend it over the Ottocast version.
These are MY experiences and others did not have some of the issues I had.

As for the MIB hack, I believe there's only 1, done through an SD card, found here: https://github.com/Mr-MIBonk/M.I.B._...ncredible-Bash
MIB wiki: https://github.com/Mr-MIBonk/M.I.B._...---install-mib

 

LOTS of great info here, thank you!

The agressive bluetooth sounds annoying enough to turn me off to both of these wireless options. I thought I read somewhere that these things go to sleep after 10 min of turning the car off?

Regarding the hack, I had originally found this: GitHub - harman-f/MHI2_US_POG11_K5186_1-MU1476-AIO: Porsche MHI2 US POG11 custom AIO FW update - it appears yours has been updated more recently so I will go with that instead. If I pay the member on the forum I will get the same exact mod or is there some extra benefit to make it worth it?

It sounds like the hack is well worth doing over the otto cast, I think I am going to cancel my order and just do the hack instead. I can probably even deal with wired android auto tbh, but I will try the wireless dongle you posted as well.

 

You're welcome. Yes, the USB port does go to sleep after sometime and I noticed it takes about 30 min for me... long enough to annoy me.

That link is for a specific head unit (POG11 K5186). The one in my link includes the various head units and selects the correct one in your car.. which truly makes it easy to do.

You don't need to pay anyone anything. The software is free to use and its complete. If you like the hack, there's a donation link if you want to toss the developer a few bucks.

I like the hack better than the Ottocast dongle for sure. I believe what makes the AAWireless dongle less aggressive is that it uses it's own app to connect to BT and not directly to the phone itself. As I'm typing this, I think you can even turn off the app via the modes and routines on your phone so it's completely invisible.

 

Thanks, I just did a dive into reading all that wiki and am going to try t he hack today. The thing is, there is a lot of stuff that isnt covered in that wiki like what all the other options do. this seems to do A LOT and doesnt really tell you which you should pick. For example I saw there is a way to change the speed setting for when android auto will play video but it says make sure you do this right in the picture but cant find any guides. Was there some guide you followed other than this wiki?

 

Did you use a full size SD card for the upgrade? I dont have any but I have tons of micro SD w/ full size adapters. The wiki says dont use a micro SD card but its my understanding they are electrically identical its just one is smaller size and that is it, so i suspect it just says this because people might have a ****ty adapter that doesnt work. Otherwise I need to order a full size SD card for just this purpose.

 

I don't know about the video speed setting but if I was to guess where it is, it's in the GEM menu. I remember there were various folders I could scroll through and select various items. I didn't do anything in there, I just wanted to see what was there. I pretty much followed the wiki instructions. Maybe send the developer these questions?

 

Regarding the post engine shutdown whine/noise - mine does the same and the one I had prior did also. I always attributed it to some sort of fuel pump or cooling thinga-majig. But I believe it is entirely normal, nothing to sweat at all.

 

Awesome! great to hear. Thanks!

 

My 2019 also does this. It stops after a few minutes.

 

What would be the easiest way to put the car on external power while I do the flashing? I have a battery tender, should I remove the plastic under the hood and connect it that way instead of connecting my battery tender clamps to the emergency fuse box connection? Is there a better way?
